This report describes a case of paravalvular leak (PVL) closure 20 days after surgery that was complicated by an
embolized 10-mm device in a patient who underwent redo PVL closure after 6 months. Waiting for 3 months
postoperatively to close a PVL is recommended. If earlier leak closure is mandatory, accepting a suboptimal result with
a moderate residual leak is advised. (Level of Difficulty: Intermediate.) (J Am Coll Cardiol Case Rep 2019;1:471–6)

P aravalvular leak (PVL) is a complication ofvalvular replacement in 6% to 15% of patients;percutaneous closure is used as first-line ther-
apy in high–surgical risk patients (1). Increasing expe-rience with percutaneous PVL closure in manytertiary centers has made this procedure relatively
EARNING OBJECTIVES
Early postoperative closure of PVL is betterpostponed for 3 months to allow stabiliza-tion of the defects to hold the closuredevices and avoid complications.If PVL closure in the first postoperativemonth is clinically indicated, acceptance ofsuboptimal results with moderate residualleaks is recommended to preventcomplications.Real-time 3-dimensional echocardiographycan guide the PVL closure procedure.

safe and efficient (2). Surgical approaches to mitralPVL have included antegrade transseptal, retrogradetransfemoral, and transapical techniques (3). Few re-ports have studied redo PVL closure, which is mostlyperformed for new PVLs; however, this procedure isfeasible and has a favorable success rate (4). Thesafety and feasibility of PVL closure in the short-term setting, within 1 month of surgery, need moreresearch. We present a case of PVL closure 20 daysafter surgery that was complicated by an embolized10-mm device in a patient who underwent redo PVLclosure after 6 months.

PAST MEDICAL HISTORY
He had undergone mechanical MV replace-ment because of rheumatic severe mitralstenosis and regurgitation 20 days earlier.After shifting the patient to the intensive
care unit, he had acute heart failure with severepulmonary congestion. Echocardiography revealed asevere PVL that the surgeon had failed to close.
EXAMINATION
The examination showed a pansystolic grade IV/VImurmur with maximum intensity at the apex andbilateral fine basal crepitations.
DIFFERENTIAL DIAGNOSIS
This patient had a clear case of decompensatedheart failure secondary to severe PVL post–MVreplacement.

INVESTIGATIONS
Transesophageal echocardiography with real-time3-dimensional (3D) imaging revealed severe PVL(Figure 1A, Video 1) with 2 large leaks at 10 o’clock and1 o’clock in the surgical view (Figure 1B, Video 2).Because of the high surgical risk in this patient, theheart team decided to perform percutaneous PVLclosure. Deployment of 2 ventricular septal defect(VSD) closure devices at the 2 leaks was planned.
MANAGEMENT
Real-time 3D transesophageal echocardiography im-ages guided the whole procedure. Device size wasdetermined by 3D full-volume imaging with colorusing the vena contracta, the effective orifice area ofthe jet, and the dimensions of the defect. The VSDdevice had a waist and 2 discs that exceeded the waistsize by 8 mm all around; this device was selected

because of the large size of the leak. Meticulousassessment of leaflet movement is mandatorybecause the left ventricular disc can trap 1 leaflet.Transseptal access was achieved using an Agilis 8.5-Ftip deflectable catheter (Abbott, Abbott Park, Illinois)to facilitate crossing the defects. The first 8-mmmuscular VSD device was deployed successfully at10 o’clock in the lateral leak (Figures 1C and 1D, Videos3 and 4). The transseptal catheter crossed the seconddefect (Figure 2A), and another 10-mm VSD closuredevice was deployed successfully and released(Figure 2B, Videos 5, 6, and 7). Both devices remainedstable in position. Transesophageal echocardiography(3D full volume with color) revealed residual moder-ate PVL medial to both devices (Video 8). Through theaortic valve, a wire crossed the leak, snared from theleft atrial cavity and exteriorized from the femoral
vein. While trying to cross the leak with a 7-F Torq-Vue delivery sheath (Abbott), the second device dis-lodged into the left atrial cavity (Figure 2C, Videos 9and 10). To snare a similar device, an assembly wasformed of a 20-mm loop snare loaded on a Judkinsright (JR) guiding catheter through a 10-F TorqVuesheath that came through the 18-F sheath in thegroin. This assembly helped the operator to catch thedevice, snare it (Figure 2D, Videos 11 and 12), andexteriorize it through the large sheath in the groin.Another larger, 12-mm device was positioned at 1o’clock with a residual moderate PVL (Video 13). Thepatient improved clinically and was discharged homeafter 1 week. Six months later, the patient still washaving shortness of breath and was in New York HeartAssociation functional class II. The patient wasadmitted for elective closure of the residual leak.

Because the leak was medial at 2 o’clock, the trans-apical axis was selected to close it. A needle for apicalpuncture was seen and a pigtail catheter landed inleft ventricular apex (Figure 4A, Video 14). Trans-apical wire passed the paravalvular leak (Figure 3Band 4B). A transapical third device was deployed,with a trace leak (Figures 3C and 4C, Video 15). Threedevices were seen in place, and the MV was fullyopened with no leaflet restriction (Figure 3D). Thefourth device closed the apical puncture (Figure 4D).The patient was discharged home at the second day.
DISCUSSION
Available clinical results for PVL closure are prom-ising, with low complication rates and high technicalor clinical success rates (60% to 90%) (5). Comparedwith surgical closure of PVL, lower mortality rates(30-day mortality rate 4.6%) have been documentedin patients treated with transcatheter closure (5).Smolka et al (6). reported transcatheter PVL closure in49 patients, 29 in the mitral position and 20 in the
aortic position. These investigators concluded thatPVL closure is feasible with a high success rate and nosignificant complications. The clinical benefits ofreduction of heart failure symptoms and hemolysisare evident after 30 days and persist up to 1 yearwithout recurrence of PVL (6). Medial leaks in the MVare better closed using transapical access because it isdifficult to cross with transseptal access. Nietlispachet al. (7) reported 2 cases of pericardial bleeding witha transapical approach with no procedural mortality.Device closure of the apical puncture is recom-mended to avoid or decrease the incidence of peri-cardial and pleural bleeding. Early postoperative PVLis mostly related to technical surgical issues. Re-ported cases of PVL closure in the first month post-surgery are rare. Manipulation of the defects in thefirst month carries the risk of enlarging the defect,thereby merging 2 or more defects and easily embol-izing the devices. If clinically feasible, we suggestwaiting for 3 months postoperatively to allow stabi-lization of the defects to hold the closure devices andavoid complications. We recommend acceptance of

suboptimal results in patients with moderate residualleaks, to prevent complications. Closure of theremaining leak after 6 months is associated with alower complication rate. However, these suggestionsrequire large clinical registries to gain more data onthe midterm and long-term efficacy of early trans-catheter PVL closure. We reported the feasibility ofretrieving an embolized 10-mm VSD closure devicefrom the left atrium through transseptal snaring andwithdrawal of the device through the interatrialseptum and femoral vein without complications.
FOLLOW-UP
During follow-up after 1 year, the patient had no moreshortness of breath and no more leakage visible ontransthoracic echocardiography.
CONCLUSIONS
Real-time 3D echocardiography can guide the PVLclosure procedure. For PVL occurring immediatelypost–valve replacement, it is better to postponeclosure for 3 months. If earlier leak closure ismandatory, we recommend accepting a suboptimalresult with a moderate residual leak to improve theclinical situation. After 3 to 6 months, closure of re-sidual leak can be performed safely. It is feasible tosnare a 10-mm muscular VSD device from the leftatrium and extract it from the femoral vein.
